Hire the Best Payments Professionals

Need AI added to your app, a workflow automated, or an MVP finished? I can help you scope it, build it, and ship it without overcomplicating the first milestone. I build AI products that survive real users, real data, and real business workflows: SaaS MVPs, AI agents, RAG systems, voice AI, and automation inside existing products. ⭐ Top Rated Plus | Top 3% of performers on Upwork ✅ 10+ years building SaaS and AI products | 100+ projects delivered ✅ AI that ships: RAG, AI agents, MCP, Voice AI, LLM integration ✅ Full stack: Next.js, React, TypeScript, Python, Node.js, PostgreSQL, AWS ✅ SaaS, MVPs, automation, fintech, healthcare, construction, legal tech, and sales products You can hire me when: - You need one AI feature added to an existing app - You want OpenAI, Claude, Gemini, or MCP integrated into your product - You need a RAG system over PDFs, documents, knowledge bases, or internal data - You want a voice AI agent for calls, bookings, lead qualification, or CRM updates - You have a workflow involving documents, calls, follow-ups, data entry, or reporting that should be automated - Your MVP is half-built, buggy, slow, or stuck before launch - You need someone to build a full SaaS product from idea to deployment I work well on both small and large projects. If the right first step is a quick audit, prototype, bug fix, integration, or one-week milestone, I will tell you that. If the project needs a full build, I can own the architecture, frontend, backend, AI layer, deployment, and documentation. The part most AI freelancers skip: AI is rarely the whole product. It usually needs a backend, dashboard, auth, billing, permissions, logs, human review, and deployment around it. I build both the AI layer and the product around it. WHAT I DO: - AI SaaS & MVP builds: idea to deployed product with auth, billing, dashboards, and AI layer - AI inside existing products: RAG, agents, MCP, LLM features, document AI, and automation - Voice AI: agents that answer calls, book appointments, qualify leads, and log to your CRM - RAG and document AI: source-grounded answers, OCR, extraction, citations, and review queues - Workflow automation: documents, follow-ups, data entry, reporting, and API integrations - Rescue & ship: half-built MVPs refactored, hardened, and launched RECENT DELIVERIES: - AI sales CRM: call transcription, follow-up automation, multi-tenant pipelines - RAG document platform with every answer cited to source - AI financial intelligence platform: open banking + accounting sync into one ledger - AI voice agents for healthcare and sales, answering real calls daily - Turnkey B2B SaaS platform for the construction industry, end to end HOW I WORK: - I start by understanding the workflow, users, data, and business goal - I suggest the smallest useful first milestone when possible - I scope clearly before code is written, so you know cost and timeline up front - I can work on focused tasks, short prototypes, rescue work, or full product builds - I work full time on Upwork with overlap for US and European business hours If you need one AI feature, a quick prototype, a stuck MVP fixed, or a full SaaS product built, send me a short description of what you have and what you want it to do. I will reply with the clearest next step, the likely scope, and the first milestone I would recommend.

STRIPE CONNECT | STRIPE BILLING | STRIPE RADAR | STRIPE API | STRIPE CHECKOUT | STRIPE TERMINAL | FINTECH | SAAS | AI | PAYMENTS | COMPLIANCE (PCI DSS, GDPR) If Stripe is slowing down your product, breaking your billing logic, or causing failed payments you can’t explain, I can fix that. I’ve delivered 100+ Stripe integrations for SaaS and tech companies, and I’m a 4× Stripe Certified professional. You’re not getting a basic integration, you’re getting a payments system designed to reduce churn, recover revenue, and scale with your growth. I specialize in building Stripe systems that directly impact metrics like churn, AOV (Average Order Value), LTV, and checkout conversion rates. I don’t just plug APIs. I step into your architecture and make sure your billing, subscriptions, and payment flows are optimized end-to-end. I can help if you’re dealing with: 🔹 High checkout abandonment rates 🔹 Unexpected churn from failed payments or poor retry logic 🔹 Broken or confusing subscription upgrades/downgrades 🔹 Low AOV due to poor pricing or payment flow design 🔹 Inconsistent or unreliable webhook handling 🔹 Stripe setups that “work” but don’t scale What I can help you with: 🔹 End-to-end Stripe integration for SaaS platforms 🔹 Subscription architecture (plans, trials, proration, lifecycle logic) 🔹 Reducing churn with smarter retry logic and dunning strategies 🔹 Checkout optimization to improve conversion rates 🔹 Webhook architecture (reliable, scalable, no missed events) 🔹 Stripe account audits with revenue-focused insights 🔹 Advanced Stripe products (Connect, Sigma, custom workflows) If you already have developers, I can work directly with them or guide them through the correct architecture in live sessions. Most Stripe implementations leave money on the table. I help you close those gaps so your payments system actually drives revenue, not just processes it. If you want to improve conversion, reduce churn, or fix hidden issues in your Stripe setup, send me a message and let’s take a look.

I design and build AI Automation systems, AI Agents, and end-to-end Workflow Automation that turn manual operations into reliable, hands-off systems. Using Makecom, n8n, Zapier, Airtable, and custom API Integration, I connect the tools you already use and add AI where it actually moves the needle: qualifying leads, drafting replies, sorting data, triggering follow-ups, and keeping your CRM clean. The systems I build are not duct-taped Zaps that break in a week. They are documented, error-handled, and built to scale as your business grows. What I build: • Makecom Automation & Scenario Design. Custom Makecom workflows that connect 50+ apps, handle complex branching logic, and replace hours of weekly manual work across operations, sales, and marketing teams. • n8n Workflow Automation & Self-Hosted Systems. n8n workflows with AI Agent nodes, RAG pipelines, and webhook integrations for businesses that want full control over their automation stack and data. • Zapier Automation & Multi-Step Zaps. Reliable Zapier automation across CRM, email, and project management tools, with proper error handling, retries, and clean Path logic that holds up under load. • AI Agent Development & AI Chatbot Systems. AI Agents and AI Chatbots built with OpenAI API, Claude API, and LangChain for lead qualification, customer support, and internal knowledge bases. • API Integration & Custom Webhook Systems. Clean REST API, Webhooks, and JSON pipelines that move data between SaaS tools that do not natively talk to each other. • CRM Automation & Lead Management Automation. HubSpot, Zoho, Pipedrive, and Airtable pipelines so leads are scored, routed, and nurtured the moment they arrive. • Marketing Automation & Email Automation. Full Marketing Automation funnels covering Email Automation, Gmail Automation, Mailchimp, and ChatGPT API Integration for personalized outreach at scale. • Google Sheets Automation & Dashboard Systems. Google Sheets turned into live dashboards with automated reporting, data syncing, and scheduled refreshes connected to your real business systems. The work consistently earns 5-star reviews, which is how the profile sits at Top Rated with 100% Job Success across 18 completed engagements. The pattern is the same across those projects: clients typically reclaim 10 to 20 hours per week, reduce manual errors significantly, and watch their lead response times drop from days to minutes once the systems go live. This work fits best with founders, agencies, consultants, and operations leaders running growing businesses who are tired of patching workflows manually and want a system that actually scales. Whether you are a coaching business automating client onboarding, a marketing agency processing inbound leads, or a SaaS team integrating internal tools, the playbook adapts. Tools and platforms: Core: Makecom, Zapier, n8n, Airtable, ClickUp, Notion, Google Workspace. AI and APIs: OpenAI API, ChatGPT API Integration, Claude API, Claude Code, Anthropic, Gemini, LangChain, RAG systems, AI Agent Development, AI Chatbot frameworks. Integration layer: REST API, Webhooks, JSON, Node.js, Python automation, data scraping, data extraction. CRM and business systems: HubSpot, Zoho, Pipedrive, Salesforce, Mailchimp, Brevo, ActiveCampaign. Web platforms: WordPress, Shopify, Webflow. Data and reporting: Google Sheets Automation, Airtable Automation, custom dashboards, scheduled reports. How we work together: Every project starts with a short scoping conversation: what the current workflow looks like, where it breaks, and what the system needs to do at the end. From there, I map the architecture, build in stages, and walk you through each piece so the system is never a black box. Communication stays in your preferred channel, response times sit inside 4 hours during the working week, and every build ships with documentation so anyone on your team can understand and adjust it later. If your business is ready to stop doing repetitive work by hand and start running on systems that scale, send an invite or a quick message describing what you are trying to automate. I will respond inside a few hours with honest feedback on whether automation fits the problem, what the right tool is, and what a clean build would look like. Let us design a system that works for you, even while you sleep.
